Abstract
The utility model discloses a centrifugal fan used in a power generator. The centrifugal fan comprises a fixed disk, wherein the fixed disk is provided with straight-plate blades which extend in an axial direction. In the centrifugal fan, since the blades are of straight plates, despite of positive rotation or reversal rotation, an air draft function is realized, heat radiation is realized, thus compared with the prior art, the fan disclosed by the utility model can be used for performing better heat radiation.
Description
Technical field
The utility model relates to generator, particularly the fan in the generator.
Background technique
In generator, the factors such as loss because of friction, wattless power can produce a large amount of heats, shed as soon as possible for making heat, and the mode that adopts is that radiating fin is set usually, to improve heat diffusion area; Improve the speed of heat transfer, it utilizes fan to realize usually, but the past all is unidirectional fan, so, in case the fan counter-rotating then not only can not be dispelled the heat, allow heat collect in the generator, but also can increase the interior pressure of generator, heat is diffused in each component fast, thereby influences the proper functioning of generator.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides the centrifugal fan of a kind of use in generator.
The technological scheme that solves the problems of the technologies described above is: a kind of centrifugal fan that uses in generator, comprise fixed tray, and axially extended straight blade is installed on fixed tray.
As improvement, on fixed tray, be provided with axis hole, on fixed tray, be positioned at and be provided with mounting hole outside the axis hole.
The beneficial effects of the utility model are: because blade is straight plate, therefore, no matter be just to change or reverse and can both realize the function of exhausting, realize dispelling the heat, therefore, with respect to prior art, utilize fan of the present utility model to dispel the heat preferably.
Description of drawings
Fig. 1 is generator Structure figure.
Fig. 2 is the stereogram of centrifugal fan.
Fig. 3 is the half sectional view of centrifugal fan.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figure 1, generator comprises stator and rotor.Stator comprises stator seat 11, silicon steel plate 12 and stator coil 13; Rotor comprises rotating shaft 21, rotor iron core 22 and rotor coil 23.Described silicon steel plate 12 is fixed on the stator seat 11, and stator coil 13 holdings are on silicon steel plate 12.Described rotor iron core 22 is installed in the rotating shaft 21, and rotor coil 23 is wound on the rotor iron core 22.
As shown in Figure 1, be with axle sleeve 3, centrifugal fan 4 is installed on the axle sleeve 3 at an end of rotating shaft.As shown in Figures 2 and 3, centrifugal fan 4 comprises fixed tray 41, axially extended straight blade 42 is installed on fixed tray 41, at the opposite side of straight blade 42 gimbal 43 is installed, fixed tray 41 and straight blade 42 are clamped in straight blade 42 between the two.
On fixed tray 4, be provided with axis hole 44, on fixed tray, be positioned at and be provided with mounting hole 45 outside the axis hole.During installation, axis hole 44 is enclosed within on the axle sleeve 3, screw passes mounting hole 45 centrifugal fan is fixedly mounted.
In the utility model, because blade is straight plate, therefore,, realize dispelling the heat no matter be just to change or reverse and can both realize the function of exhausting, therefore,, utilize fan of the present utility model to dispel the heat preferably with respect to prior art.
Claims (2)
